3.1.6: Metallic bonding + structure Flashcards
1
Q
What is the structure of a giant metallic lattice?
A
a lattice of positive ions arranged in a regular pattern surrounded by a sea of delocalised electrons which are free to move and are balanced across the whole structure
2
Q
what are the properties of giant metallic lattices
A
high melting + boiling points
good electrical conductors
malleable
ductile
3
Q
what is a ductile metal?
A
a metal that can be made to stretch
4
Q
why do they have a high melting and boiling point?
A
the intermolecular forces between the electrons and the positive ions is very strong and therefore requires a lot of energy to break
5
Q
why are they good conductors of electricity?
A
the delocalised electrons are free to move and can therefore carry a charge
